If 100 healthy individuals are tested with that method, only 90 of those 100 healthy people (90%) will be found normal (disease-free) by the test. The other 10 people (who do not have the disease) will appear to be positive for that test. For that 10%, their abnormal findings are a misleading false-positive result.or example, a certain test may have proven to be 90% sensitive. If 100 people are known to have a certain disease, the test that identifies that disease will correctly do so for 90 of those 100 cases (90%).
The width of a doorway inside a building that you frequently visit, is a measurement that is hardly ever brought up or talked about. To meet the ADA accessibility standard, doors must have a clear width of 32 inches from the face of the door to the opposite stop.
If you are dealing with the existing framing on your own, remember that handicap doorways should have at least 32 inches of space to accommodate the width of the chair, and the doors should swing outward.
